A solid old-town trattoria run by the same family for decades, Al Pozzo is tucked into the caruggi near the main square. The menu sticks to what the coast does well: fritto misto, stuffed anchovies, grilled branzino, and a simple farinata that appears most afternoons. Prices are honest and the atmosphere is properly local.
Go for lunch rather than dinner if you want the quieter version. The terrace out front catches the afternoon shade.
